How do you pick up an item with the drowsing machine n pokemon platinum? I geuss it would be like Pokemon Diamond and Heart Gold. I love pokemon and from my experiences, when the drowsing machine beeps at a rapid pace in one place, press A (if on DS) even though nothings there. This answer is coming from a girl so that's pretty cool for me!
the drowsing machine is a tool that lets you find items that you cant see without it
You get it in Narcene city from Bianca
You just look around beach's and have your drowsing machine out looking until you find one!
You go to Ecruteak City and go to a house near Burned Tower and talk to the man there answer Yes and he will give you the dowsing machine
It is outside the reception room. Warning if you are standing on the dot on your drowsing machine you wont find it.
In that one place by that cool place in that one town where Pokemon are.

Dawn or Lucas gives it to you at the end of Cycling Road.
First, go to Hotel Grand Lake which is near Lake Valor. Talk to the lady standing near the door. She lost her hotel key so with your poketch, go to drowsing machine. Once you find the key, talk to the lady again. She will reward you with the white flute.
